Ram Pass
Peak · 11,376 ft · Mammoth Lakes corridor
Ram Pass is an 11,376-foot peak in the Mammoth Lakes corridor of the Sierra Nevada, with avalanche terrain and high-altitude exposure. Expect relentless wind and sparse crowds.
Wind dominates Ram Pass. The 30-day average of 15 mph understates the afternoon pattern; gusts regularly exceed 40 mph by mid-day as thermals funnel through the saddle. Morning calm is the rule before 10 a.m. Snowpack stability and rime ice are the dominant hazards in winter and spring.
Over the last 30 days, Ram Pass averaged a 36 NoGo Score with a 15 mph average wind and temperatures near 23 degrees Fahrenheit, reflecting spring conditions at elevation. The week ahead shows typical April variability; watch for afternoon wind spikes and assess avalanche terrain before any ascent.

About Ram Pass
Ram Pass sits at 11,376 feet on the spine of the Mammoth Lakes corridor, a high-altitude saddle accessible primarily from the Mammoth Mountain area. The approach via the Inyo National Forest involves significant elevation gain and exposure to avalanche terrain; the peak is not a casual hike. Winter and early spring demand glacier travel skills and current ESAC avalanche forecasts. Summer and early fall offer the most straightforward access, though afternoon wind remains the dominant hazard. Base popularity is low because the approach is technical and the views do not justify the objective hazard for casual visitors.
Ram Pass experiences the full force of Sierra weather. The 30-day rolling average wind of 15 mph is conservative; gusts regularly reach 43 mph, particularly in afternoon. Spring and early summer see the most extreme wind days as thermal circulation amplifies across the high passes. Temperatures swing from a 365-day low of 10 degrees Fahrenheit in winter to 36 degrees Fahrenheit in summer, with the current 30-day average of 23 degrees Fahrenheit reflecting late April conditions. Crowding averages only 2 out of 10, a reflection of the technical approach and sustained high wind. Snow lingers into June most years; wet-slab avalanche risk peaks in late morning as solar loading increases.
Ram Pass is for experienced mountaineers and backcountry skiers with avalanche awareness, not day hikers or casual visitors. Plan morning departures to minimize wind exposure and maximize visibility of rime ice and cornices. Afternoon wind can exceed 40 mph and reduce visibility to zero within minutes. A current avalanche bulletin from ESAC is non-negotiable in winter and spring. Bring more layers than you think necessary; temperature drops and wind chill combine to create extreme cold even on days when sheltered valleys feel mild. Parking at the Mammoth Mountain base or nearby trailheads fills quickly on weekends; arrive before dawn.
Ram Pass is one of the few true 11,000-plus-foot summits in the Mammoth Lakes corridor that remains accessible to foot traffic. Nearby Mammoth Mountain itself is more frequented but more crowded and commercial. The approach to Ram Pass via the high ridges is more technical and rewards mountaineering skill over luck. If you cannot read avalanche terrain, manage wind exposure, or navigate by compass, choose a lower alternative in the corridor; the consequences of error at Ram Pass are absolute.
